SPARK-ARRESTER.

SPECIFICATION forming part of Letters Patent No, 308,500, dated November 25, 1884.

Application filed May 523, 1884.

T0 or whom, it may concern.-

Be it known that I, J AMES A. J ONES, a citizen of the United States, residing at Tyler, in the county of Smith and State of Texas, have invented certain new and useful Improvements in Spark-Arresters; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable oth. ers skilled in the art to which itappertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a vertical sectional view of my device. Fig. 2 is a top view of the same, and Fig. 3 is a transverse sectional view.

This invention has relation to means for pre venting the discharge of burning cinders or sparks from smoke-stacks, especially those of locomotive-engines; and it consists in the construction and novel arrangement of devices, as hereinafter set forth, and pointed out in the appended claim.

In the accompanying drawings, the letter A designates the wall of a smokestack, and B an interior cylinder, consisting of an upper portion, 0, and alower portion, D, these portions being separated by an annular opening or interval, E.

Between the portions of the inner cylinder and the inner wall of the outer cylinderis arranged an interspace or flue, g, which at its lower end communicates with pipes or passages 71 leading to a box or reservoir at some convenient point under the engine.

Around the upper portion, 0, of the inner cylinder is secured an upwardly-flaring collarflange, is, above which the top of the cylindersection extends upward even with the top of the stack, as indicated at Z. The flange It forms the top of the interspace or flue g, which communicates with the main smoke passage I (No model.)

through the inner cylinder by the annular opening E. The upper portion of the flue g, or that portion around the opening E, is subdividedinto two cylindrical passages, s and t, by an intermediate cylindrical guard or partition, F, which is designed to prevent the burning cinders which pass through the opening E from the main sn1oke-passage I from returning into said passage on the downward current.

In the upper part of the main smoke-passage I, and bridging the annular opening E,

is located a spiral guide, G, having wings H, which extend from the central or axial line, where they intersect, outward, to the inner walls of the upper and lower sections, 0 and D, of the inner cylinder.

By means of the spiral guide-wings H the burning cinders or sparks are directed through the opening E into the cylindrical flue g, whence they are conducted into a box or reservoir.

The intermediate partition, F, maybe conveniently supported by lugs 2, extending outward from the wall of the lower section, D, of the inner cylinder.

Having described this invention, what I claim, and desire to secure by Letters Patent, 1s

The combination, with the stack, of the upper and lower portions, 0 and D, of the inner cylinder, separated by the annular opening E, the. spiral wing-guide G, the collarflange between the stack-wall and the section (J, and the cylindrical partition F below said collarflange in the flue g, substantially as specified.

In testimony whereof I affiX my signature in presence of two witnesses.

JAS. A. JONES.
